summary: 'TODO(https://go.dev/issue/56443): fill in summary field'
description: |
    Some big.Int values that are not valid field elements (negative or overflowing)
    might cause Curve.IsOnCurve to incorrectly return true. Operating on those values
    may cause a panic or an invalid curve operation. Note that Unmarshal will never
    return such values.
